This should most prob' be in the tech section.....but i really need urgent help!

One of my cars, MK2 Golf GTI 8v has a Cobra alarm on. Today I decided it would look good with gold terminals on the battery instead of the metal old things. Cleaned up all terminals, earthing points etc and put all back together. Tried starting my car and it would not start, a constant buzzing noise with a horrible smell of petrol. Kept trying, hazard lights flashing, dash illumination gone, wipers going on and off etc etc.

Anybody know how to strip a Cobra alarm or is there a way I can fix it?


Sorry for putting this in General section but need my car for a very important appointment at 11am tom' morning.

Many thanks in advance
